WINDOW.

Specification of Letters Patent.

Patented May 16, 1916.

Application filed March 22, 1915. Serial No. 16,281.

To all whom it may concern:

Be it known that I, Josnrrr Jones CLEM- ENT WARREN, a subject of the King of Great Britain, residing at Murray Bay, Charlevoix county, Province of Quebec, Canada, have invented certain new and useful Improvements in Windows; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to windows.

The object of my invention is to provide a movable guiding means for vertically mov able sash which will permit the sash being rotated on a horizontal axis.

A further object is to provide a guide and pivot member of such construction as to per mit attachment thereto of a sash cord, to avoid wear on the cord.

My invention consists of the construction, combination and arrangement of parts, as herein illustrated, described and claimed.

In the accompanying drawings forming part hereof, I have illustrated a form of em bodiment of my invention, in which drawings similar reference characters designate corresponding parts, and in which:

Figure 1 is a front elevation partly broken away; Fig. 2 is a vertical section taken ap proximately on line 22 of Fig. 1 looking in the direction indicated by the arrows; Fig. 3 is a horizontal section taken approximately on line 33 of Fig. 1 looking in the direction indicated by the arrows; and, Fig. 4: is a fragmentary detail in elevation of the pivot member and its immediately connected parts.

Referring to the drawings 1 designates a lower and 2 'an upper sash of common construction, provided with grooves 3 and 4 respectively, nearly the whole length of the stiles thereof.

Grooves 5 and 6 are formed in the opposite sides of the frame of the window, which Copies of this patent may be obtained tor five cents each, by addressing the Washington, D. G.

frame is also of common construction. The grooves 3 and 5 and 4: and 6 correspond in position and arrangement to form channels for balls 7 and 8, respectively.

As shown in the drawings the balls 7 and 8 working in the grooves 85 and l-6 form pivots to permit axial rotation of the sashes, and at the same time serve as guides for the vertical movement thereof.

Each of the balls 7 and 8 is provided with a peripheral groove 9 in which is disposed the looped lower end 10 of the sash cord 11. The sash cord is carried over the pulleys 12 and the opposite end attached to a weight 13, as in common practice, the weight working vertically in the box portion 11 of the caslng.

l/Vedges 15 are carried by the sashes and work in suitable openings in the casing in order to lock the sashes at suitable points. Hinged strips 16 are disposed on the casing, and strips 17 are disposed on the sashes to work in grooves 18 in the casing, for the purpose of making a joint to prevent the passage of air, as well understood in the art.

iaving thus fully described my invention, what I claim as new and desire to secure by Letters Patent is:

A window comprising a frame provided with vertical grooves in its opposite sides, sashes slidably disposed in the frame and provided with corresponding grooves, balls movably disposed in adjacent grooves in the frame and sashes and provided with peripheral grooves, cords each having one of its ends disposed in the grooves, and a counterbalance at the opposite end of each of the cords.

In witness whereof I have hereunto set my hand in the presence of two witnesses.
